I would like to see pics of what guys have broken or post up were they were breaking at. Is it the main shaft or other? I have the complete rear out of my car right now and have had some 300m axles on the shelf for over a year just been waiting for the stockers to break. Not sure what the record is but I think I may squeeze out a high 9 this season and is it worth it to do it on stock axles (record) or has that been done already?

 

Couple of mine that broke before I got Drivelineshop axles.

 

BTW... that was with about 400 RWHP

 

Marko from forcefed in BC claims to have the fastest stock-driveline (including axles) RX7: https://www.rx7club.com/canadian-forum-42/worlds-fastest-stock-drivetrain-rx7-920230/

 

oh well, guess I will be going for first FD on stocker's. I am pretty sure enzo's little bro was on cobra IRS.

 

Mike,

Here is my break on my FD, think is was driver's side inner. Had about 440 wheel hp (V8).

Damn clean break!

 

That's a nice break! Was that on drag tires?

I have a couple events in the next 2 weeks. If I don't break them or if I hit my goal I will swap them then.

 

I've got a collection of pics of the inner cup snapping off right at the splines, hoping the magic valve prevents this as i only have 1 more cup.... then the 8.8 in my shed will come out lol

 

Stock axles....

 

What did your car run in that video et wise? Or did you break an axle on that pass?

 

It was on ET Streets, car didn't move an inch when it happened....3,500 on the 2-step, released the clutch (not dumped) and bam!...I was very surprised!

 

Means you are hooking well. I try to spin the tire some. That and pre loading the driveline. I do dump the clutch. My gut tellms me I will break tonight. This new clutch set up hits hard. The old 6 puck would slip but the iron disk doesn't.

 

Good luck tonight!!! Let us know how it goes.

 

Show me that 5.9s pass lol

 

Well axles are still there. Car was acting up. A little. Think the plugs are bad. Clutch was perfect Hits hard! bad tire spin so 60 foots were 1.6's to 1.7's. Tried different tire pressure, 2step rpm's, free revs, etc... I can't believe I hooked better with my stock wheels and et streets. I have more sidewall on these 15's. 6.6's all night like I was a bracket racer. Was running lower boost than usual.

But something sounds a little funny in the rear,...

 

You're just paranoid.

 

You ready for next weekend?

 

Removed rear tires and drivers side had one bolt half way out and other one missing off brake caliper! Oops!


I am ready for next weekend I guess. Thinking about the heat just kills me. Friday here is 96 so would guess Montgomery is going to be even hotter. I can't believe they are doing a day race instead of night. Think I am going to run my oem wheels for first qualifying pass. Not sure if I am going to run modified or rwd class. I would prefer to run modified and let you clean house in rwd but don't think I have a chance against the alpha 10 gtr! Also looking at my logs from last night it was spiking between shifts and I was just looking at peak psi after each run. So I was running only like 1.5 to 1.7 max boost thru the gears. Definitley more left. Mph was lower than usual @ 108.
